高水速凝材料渗透特性试验研究

Research on seepage properties of high water quick-setting material and its mechanism analysis

采用自主改进的TST-55型变水头渗透仪,试验研究了不同水灰比、龄期及使用淡水、海水时高水速凝材料的渗透性,并分析了其水化反应机理,指出高水速凝材料渗透系数随着龄期的增长不断减小;随着水灰比的降低而减小;海水可使该材料的渗透系数变高。

This paper used the self improved TST-55 type falling head permeameter,tested and researched the permeability coefficient of rich water accelerated material decreased with the increase age of different water cement ratio,age and use of fresh water,sea water,decreased with the decrease of water cement ratio,the water permeability coefficient of the material was high of sea water.
